Public parking of the National Park Loonse en Drunense Duinen. Free and very quiet once the hostel closed. At the entrance of the woods and at the foot of the big dune, ideal to spend the night before a visit to Efteling; )

Stayed here one night, very quiet after the restaurant closes at 10pm however it is an official car park for the national park and I don't think it is officially permitted to stay here so we woke early and left
